WINDMILL.

SPECIFICATION forming part of Letters Patent No. 254,527, dated March 7,1882.

Application tiled December 14, 188i. (Model.)

and exact description of the invention, which willenable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings,

which form a part of this specification.

My invention relates to certain improvements in geared windmills, andhas for its principal object to avoid the side drafts of wind which arecommon to ordinary geared windmills, and sometimesprove very disastrousthereto, by providing means for throwing the wheel out of gear. Afurther object is to so construct and arrange the gear-wheels that thewind-wheel will readily shift with the Wind.

These objects I attain by means of the devices illustrated in theannexed drawings, in which-A Figure lis a vertical central section; Fig.

2, a similar section taken on a plane at right' angles to Fig. 1. Fig. 3is a horizontal sectional view, and Fig. 4. is a central verticalsection of a somewhat modified construction.

Referring by letter to the accompanying drawings, A indicates the framewhich supporlts the several operative parts of the windmil B refers tothe horizontal windwheel shaft, which has its bearings in standards b b,that are secured tothe turn-table C of the windmill.

A bevel-gear,D, provided with an elongated hub or sleeve, d, is looselymounted upon the wind-wheel shaft, and it is rigidly connected with aring-gear, E, by means of the divergent arms F, that are in rigidconnection with the sleeve of the said bevel-gear.

A crank-arm, G, is connected with the windwheel shaft at a pointalongside of the ringgear, and upon the wrist-pin of this crank-arm is asmall loose gear, H, which meshes with the internal gear-teeth of saidring-gear, and which also gears with a spur-gear, t', that is rigidlysecured to a large miter-gear, I. This miter-gear is loosely mountedupon the windwheel shaft, and is adapted t0 mesh with a horizontalruiter-gear, K, that is mountedloosely upon the vertical shaft L. Aninternallytoothed gear, M, is formed with or secured to the under sideof the horizontal ruiter-gear K,

and upon al horizontal arm, N, that is held stationaryjust abovetheturn-table, is arranged a small spurgear, n, which engages with theinternal teeth ofthe ring-gear M. This small spur-gear n also engageswith a spur-gear, O,

which is rigid upon the vertical shaft L. The 6o horizontal arm uponwhich said spur-gear is mounted is provided at its outer end with avertical pivot for the spur-gear, and at its inner end it is connectedwith a stationary tubular bearing, P, which is secured to thesupporting-frame, and through'which the vertical shaft passes. Thistubular bearing passes through the turn-table, and also constitutes theaxis about which the latter turns.

The vertical shaft L, which is employed for 7o the purpose of actuatingthe pump or other mechanism to be driven, has a bearing at its upper endin a cross-bar, l, that is secured to standards upon the turn-table, andupon said shaft, below the crossbar, is rigidly secured a bevel-gear, Q,which meshes with the large bevel-gear D, that is mounted upon thewindwheel shaft, as already described.

When the wind-Wheel shaft is revolved the bevel-gear D will revolvetherewith by reason of 8o the spur-gear H meshing with the gear 'i andthe rin g-gear E, which latter is, as before stated, in rigid connectionwith the bevel-gear D. This bevel-gear will then rotate the shaft Lthrough the medium of the bevel-gear Q, that is secured to said shaft.During such movement on the part' of the bevel-gears D and Q thehorizontal miter-gear, engaging with the miter-gear I, will revolve in adirection reverse to the revolution of the' vertical and the bevel-gearQ, 9o which, as aforesaid, is secured upon said shaft;

Thus as the vertical shaft rotates about its axis it carries with it thespur-gear O, which is rigid with said shaft. The horizontal miter-gearK,

moving with the vertical miter-gear I, will reas this spur-gear revolvesit will, by reason of roo its engagement with the spur-gear O upon shaftL, turn in a direction reverse to the movement arms F, as in Fig. l.

The miter-gear I is attached to the Windwheel sh aft B, and meshesdirectly with a mitergear, K, that is rigid upon the vertical shaft L.

is a spur-gear rigid upon the wind-wheel shaft B, and (I indicates anarm loosely mounted upon said shaft and provided with pivots, upon whichare loosely mounted the spur-Wheels H. These spur-gears engage with andserve to connect the internally-toothed ring-gear E, which is rigid withgear D, with the spur-gear i, that is rigid upon the Wind-Wheel shaft B.

Upon the vertical shaft L is a loose bevelgear, Q, which is engaged bythe bevel-gear D. This bevel-gear Q is provided upon its under side withan internal gear, M, with which the spur-gear n upon the station ary armN engages. This spur-gear also engages with a spur-gear, O, that isrigid upon the shaft L, and upon the upper end of this vertical shaft isthe mitergear K, arranged to engage with the miter-gear I upon thewind-Wheel shaft. It will be seen that in both instances the sameobjects are attained, the wheels or gears D and I being opposite eachother, and the remaining gears bev'ing practically the same in bothcases.

The above arrangement admits of the wheel and turn-table readilyshifting with the Wind.

'Ihus when th'e wind shifts the gear D Will ride Having thus describedmy invention, what I claim is l. The combination, in a Windmill, ofbevelg'ear and the mitergear upon the wind-wheel shaft, with thebevel-gear and the miter-gear rotating `about the axis of the verticalshaft and driven in opposite directions, one of said last two mentionedgears being rigid upon the vertical shaft, and the other being looselyarranged and connected by a spur-wheel with a spur-gear upon thevertical shaft, substantially as described.

2. The combination, with the horizontal Windwheel shaft, ofthe loosebevel-gear D, connected with an internally-toothed gear, E, and engagingwith a bevel gear that is rigid upon the vertical shaft, the miter-gearI, engaging with the miter-gear K, the arm upon the horizontal shaftcarrying a loose spur-gear engaging the internally-toothed wind-gear Eand the spur-gear i, the spur-gear n upon a stationary arm, N, and thegears 0 andQ upon the vertical shaft, said members being combined andorganized for operation substantially as described.

3. The combination of the horizontal shaft B with the bevel-gear D, thebevel-gear Q upon the vertical shaft, the miter-gears I and K, thespur-gears n O, and the internal gear, M, constructed and organized foroperation substantially as specified.

In testimony thatIclaim the foregoing as my own I have hereto affixed mysignature in presence of two witnesses.
